I have had a very busy morning with errands.  I needed a new inner tube for my front bike tire.  It wasn't holding air.  So I  bought a new one and replaced it.  Then I went on a bike ride so cross training for today.  I only rode for 45 min.  My back was hurting and I was having a lot of trouble breathing, so I didn't ride for the full hour.  Maybe I'll go for a walk later.

It\'s hot here today and outdoor exercise would be a challenge. I went to the pool instead. Am trying to think of some water exercises I can do to strengthen my legs now that I\'m committed to the knee surgery.
